Poker is a card game in which the players try to form five-card hands that are as good as possible. The best hand wins the pot. For example, a pair of kings is a very strong hand and will beat any other hands.

There are a number of variations of the game, but most versions follow similar rules. The game can be played by two to four players and is usually played with a deck of 52 cards.

A player begins the game by betting a small amount, called an ante. This bet gives the pot a value right away and is an important part of the game’s structure.

During the course of play, players can choose to raise or fold their bets and cards. This is a decision made after looking at the bets of other players and comparing their hands with each other.

It is also possible to bluff other players, a technique that can be used to increase one’s chances of winning. By bluffing, you can make other players think that you have a good hand when you don’t.
